In fact, trying to power the NXT motors under high-load conditions from an RCX would (I think) be likely to trip the thermal protection in the RCX, and shut down the outputs temporarily.<BR/><BR/>-- <BR/>Brian DavisBrian Davishttp://www.blogger.com/profile/13348160352741782598noreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1150124278937334432006-06-13T00:57:00.000+10:002006-06-13T00:57:00.000+10:00Short answer is that RCX cannot control NXT motors...Short answer is that RCX cannot control NXT motors, even via converter cable.<BR/><BR/>I can't find the specific website that detailed that information, but I'm recalling that it was somewhere on LEGO Education.<BR/><BR/>The main reason is that RCX Lego Motors are controlled by turning power on and off, versus changing the voltage as is done in the NXT Motors. Basically, the RCX doesn't know how to change power for a NXT motor.byronczimmernoreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1150077103958586072006-06-12T11:51:00.000+10:002006-06-12T11:51:00.000+10:00Can any of you robotics geeks tell me if an NXT mo...Can any of you robotics geeks tell me if an NXT motor will work when plugged into an RCX motor port via converter cable (the rotation sensor wouldn't work, of course, but just the motor itself)?<BR/><BR/>William, a small-time inventor [who probably doesn't know what he's doing]William L.
